Mortar yog cov khoom siv tseem ceeb hauv tsev siv hauv ob qho tib si loj thiab me me. Nws feem ntau muaj cov cement, xuab zeb thiab dej nrog rau lwm cov khoom ntxiv. Txawm li cas los xij, nrog kev nce qib ntawm thev naus laus zis, ntau cov khoom siv ntxiv tau qhia los txhim kho lub zog sib txuas, hloov tau yooj yim thiab dej tsis kam ntawm mortar.
Ib qho ntawm cov kev qhia tshiab tshaj plaws nyob rau hauv lub ntiaj teb ntawm cov tshuaj khib nyiab yog kev siv cov khoom siv polymers. Binder polymers yog cov khoom siv hluavtaws uas txhim khu lub zog ntawm mortars. Lawv tau ntxiv rau hauv lub mortar thaum lub sij hawm sib tov thiab hnov mob nrog cov cement los ua ib daim ntawv cog lus muaj zog. Kev siv cov polymers khi tau pom los txhim kho cov cuab yeej cuab tam ntawm mortars, ua rau lawv tiv taus ntau dua rau kev tawg thiab dej nkag.
Lwm qhov ntxiv uas tau ua nrov nyob rau xyoo tas los no yog redispersible polymer hmoov (RDP). RDP yog ib qho polymer siv los txhim kho cov khoom ntawm mortars. Nws yog tsim los ntawm kev sib tov ntawm polymer resins uas tom qab ntawd tov nrog cement hmoov, dej thiab lwm yam additives. RDP tau dhau los ua neeg nyiam vim nws muaj ntau yam thiab cov khoom tshwj xeeb.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv RDP hauv mortar yog nws lub peev xwm los ua kom yooj yim ntawm cov khoom tiav. Qhov tshwj xeeb no yog qhov tseem ceeb tshwj xeeb hauv thaj chaw uas cov tsev muaj kev pheej hmoo rau av qeeg thiab lwm yam kev puas tsuaj ntuj tsim. Cov mortars ua nrog RDP tau raug pov thawj tias muaj zog dua, hloov tau yooj yim thiab tsis tshua muaj kev tawg nyob rau hauv siab. Tsis tas li ntawd, RDP tuaj yeem txhim kho cov dej tsis kam, ua rau nws muaj txiaj ntsig zoo ntxiv hauv thaj chaw uas muaj dej nag ntau.
Ntxiv nrog rau kev txhim kho kev yooj yim thiab dej tsis kam, RDP kuj tseem txhim kho kev ua haujlwm ntawm cov mortar. Nws xyuas kom meej tias cov mortar kis tau thiab teeb tsa sib npaug, ua kom yooj yim rau cov neeg tsim khoom. Qhov no yog qhov tshwj xeeb tshaj yog thaum tsim cov phab ntsa, cov plag tsev, thiab lwm qhov chaw uas yuav tsum tau ua kom tiav. RDP kuj txo cov dej uas xav tau thaum lub sij hawm sib tov, ua rau muaj kev sib txuam ntau dua nrog cov voids tsawg.
Kev siv cov tshuaj mortar additives xws li khi polymers thiab redispersible polymer hmoov yog revolutionizing kev lag luam kev tsim kho. Cov mortars uas muaj cov tshuaj ntxiv no muaj zog dua, hloov tau yooj yim dua thiab tiv taus dej ntau dua, ua kom lub tsev ruaj khov thiab kav ntev. Nws yuav tsum tau muab sau tseg tias cov additives no yuav tsum tau siv nyob rau hauv cov proportions tsim nyog. Cov piv txwv pom zoo los ntawm cov chaw tsim khoom yuav tsum tau ua raws li kom tsis txhob cuam tshuam qhov zoo ntawm cov mortar.
Kev tsim kho kev lag luam yog hloov zuj zus mus tas li thiab ntau yam kev txhim kho hauv cov khoom siv hauv tsev yog qhov zoo siab. Kev siv cov khoom siv ntxiv hauv mortars, xws li khi cov khoom siv polymers thiab cov khoom siv rov ua dua tshiab, yog ib kauj ruam ntawm txoj hauv kev los xyuas kom meej cov qauv ruaj khov thiab muaj zog dua. Cov khoom siv ntxiv no ua kom lub tsev tuaj yeem tiv taus kev puas tsuaj ntuj tsim, dej nyab thiab lwm yam uas tuaj yeem cuam tshuam nws txoj kev ncaj ncees. Yog li ntawd, qhov kev nce qib no yuav tsum tau txais thiab siv los tsim cov qauv zoo dua thiab muaj zog dua yav tom ntej.
